B.
Wherever a private contractor works in or around a public highway,
road, street or right-of-way or any Town water or sewer mains, utilities,
or fixtures, the contractor shall be responsible for repairing or
maintaining the right-of-way area, fixtures and mains during construction
and for a period of one year after completion of the work. The contractor
shall be responsible for restoring the excavated or damaged portions
of such highway, road, street or highway, and water or sewer mains
to the condition prior to such work, excavation or damage. During
construction and for the following one-year period, the contractor
shall also be responsible for all claims for personal injury and property
damage resulting from the improper or inadequate repair or restoration
of the highway, road, street, right-of-way, or water or sewer main.
Any and all stumps, trees, bushes, boulders,
organic materials or building footings and foundations in the line
of any proposed construction within the public right-of-way or easement
shall be fully removed and legally disposed of by the developer or
contractor. Trees to be maintained shall be trimmed and protected
during all phases of the construction. All damaged trees should be
repaired and painted with an asphaltum base paint. All topsoil shall
be stockpiled in an area approved by the Town.
A.
Temporary sheeting shall be used to maintain vertical
trench walls in all excavations in paved areas and in areas requiring
protection of adjacent structures, foundations and utilities. The
sheeting and bracing shall be sufficient to sustain the sides of the
excavations and to prevent collapse of trench walls which could in
any way injure the work, adjacent pavement, structures, foundation
or utilities. Any new or existing structures which are damaged through
settlements, water or earth pressures, slides, cave-ins or other causes
due to failure or lack of adequate sheeting or bracing, improper bracing,
or through negligence or fault of the developer in any manner, shall
be repaired by the developer at his or her own expense. Safety requirements
of Section 552 of the New York State Department of Transportation
(DOT) Specifications shall apply to all work regulated by this article.
B.

Concrete shall be handled from mixer to transport
vehicle to place of final deposit in a continuous manner as rapidly
as practicable and without segregation or loss of ingredients until
the approved unit of operation is completed. Placing will not be permitted
when the sun, heat or limitations of facilities prevent proper finishing
and curing of the concrete. Concrete shall be placed in the forms,
as nearly as practicable in final position, in uniform approximately
horizontal layers not over 12 inches deep. Forms or reinforcement
splashed with concrete shall be cleaned in advance of placing subsequent
lifts. Concrete shall not be allowed to drop freely more than five
feet in unexposed work nor more than three feet in exposed work; where
greater drops are required, a tremie or other acceptable means shall
be employed. Concrete to receive other construction shall be scalded
to the proper level to avoid excessive shimming or grouting. Conduits
and pipes shall not be embedded in concrete unless specifically indicated.
B.
Concrete that is truck-mixed or transported in truck
mixers or truck agitators shall be delivered to the site of the work
and discharge completed in the forms within the time specified in
the ASTM Specification C 94. Transit-mixed concrete that is completely
mixed at the site of concrete placement or batched cement and aggregates
transported to mixers shall be placed in the forms within 11/2 hours
after cement has been added. Concrete shall be placed in the forms
within 15 minutes after discharge from the mixer at the job site.
C.
Temperature requirements. Concrete shall not be placed
without special protection when the concrete is likely to be subjected
to freezing temperatures before the expiration of the specified curing
period. If it is necessary to place concrete under conditions of low
temperature, said placement shall not be done without prior approval
of the Town. Temperature of the concrete when placed shall be not
less than 50° F. nor more than 70° F. Heating of mixing water
and/or aggregates will be required as necessary to maintain minimum
concrete temperature of 50° F., and all methods and equipment
for heating shall be subject to acceptance. Materials shall be free
from ice, snow, frost and frozen lumps before entering the mixer.
Surfaces that will be in contact with concrete shall be free of frost,
ice or snow. Suitable covering and other means that will not stain
concrete, as approved, shall be provided for maintaining the concrete
at the temperature and periods specified. Concrete shall be kept above
freezing temperatures until surface defects have been remedied. Salt,
chemicals or other materials shall not be mixed with the concrete
to prevent freezing. Any concrete damaged by inadequate protection
or procedure shall be removed and replaced at no additional cost to
the Town.
D.
Concrete placed against earth. Concrete shall be placed
upon undisturbed surfaces. The surfaces shall be clean and free from
frost, ice, mud and water. Waterproof paper, polyethylene sheeting
of nominal 4-mil minimum thickness or polyethylene-coated burlap shall
be laid over surfaces receiving concrete, and specified for curing
concrete, except that the polyethylene film may be other than white.
E.
Compaction of concrete. Immediately after placing,
each layer of structural concrete shall be compacted by internal concrete
vibrators supplemented by handspading, rodding and tamping. Tapping
or other external vibration of forms will not be permitted. Vibrators
shall not be used to transport concrete inside forms. Internal vibrators
submerged in concrete shall maintain a speed of not less than 7,000
impulses per minute. The vibrating equipment shall at all times be
adequate in number of units and power to properly consolidate all
concrete. Spare units shall be on hand as necessary to ensure such
adequacy. Duration of vibration shall be limited to time necessary
to produce satisfactory consolidation without causing objectionable
segregation. The vibrator shall not be inserted into lower courses
that have begun to set. Vibrators shall be applied at uniformly spaced
points not farther apart than the visible effectiveness of the machine.
Joints shall be constructed in strict accordance
with Section 502-3.08 of the NYSDOT Standard Specifications.
A.
All steel reinforcement for concrete shall comply
with the latest standards and specifications of the following agencies:
A.
The curing of concrete shall be accomplished using
the following methods:
|
Type
|
Method
|
|---|---|
|
General concrete work and structures
|
Moisture or impervious sheet curing
|
|
Concrete pavements except sidewalks and drives
|
Impervious sheet or membrane-forming compound
curing
|
B.
All curing shall be adequately maintained by the developer.
C.
The developer shall provide curing in the appropriate
manner as listed below:
(1)
Moist curing. Unformed surfaces shall be covered with
burlap or mats, wetted before placing, and overlapped at least six
inches. Burlap or mats shall be kept continually wet and in intimate
contact with the surface. Where formed surfaces are cured in the forms,
the forms shall be kept continually wet. If the forms are removed
before the end of the curing period, curing shall be continued as
on unformed surfaces, using suitable materials.
(2)
Impervious-sheet curing. All surfaces shall be thoroughly
wetted with a fine spray of water and be completely covered with waterproof
paper, or polyethylene sheeting, or with polyethylene-coated burlap
having the burlap thoroughly water-saturated before placing. Covering
shall be lapped not less than 12 inches and securely weighted down
or shall be lapped not less than four inches and taped to form a continuous
cover with complete closed joints. Sheets shall be weighted to prevent
displacement or billowing from winds. Sheets shall be immediately
repaired if tears or holes appear during the curing period.
(3)
Membrane-forming compound curing. Before applying
curing compound, tops of joints that are to receive sealer or sealant
shall be tightly closed with temporary material to prevent entry of
the compound and to prevent moisture loss during the curing period.
The compound shall be applied on damp surfaces as soon as the moisture
film has disappeared. The curing compound shall be applied by power-spraying
equipment using a spray nozzle equipped with a wind guard. The compound
shall be applied in a two-coat continuous operation at a coverage
of not more than 400 square feet per gallon for each coat. When application
is made by hand sprayers, the second coat shall be applied in a direction
approximately at right angles to the direction of the first coat.
The compound shall form a uniform, continuous, adherent film that
shall not check, crack or peel and shall be free from pinholes or
other imperfections. Surfaces subjected to heavy rainfall within three
hours after compound has been applied, or surfaces damaged by subsequent
construction operations within the curing period, shall be resprayed
at the rate specified above. Membrane curing compound shall not be
used on surfaces that are to receive any subsequent treatment that
depends on adhesion or bonding to the concrete. Membrane curing compound
shall not be used on surfaces that are maintained at curing temperatures
with free steam. Where membrane-forming curing compounds are permitted,
permanently exposed surfaces shall be cured by use of a nonpigmented
membrane-forming curing compound containing a fugitive dye. Where
non-pigmented-type curing compounds are used, the concrete surface
shall be shaded from the direct rays of the sun for the curing period.
Surfaces coated with curing compound shall be kept free of foot and
vehicular traffic and from other sources of abrasion and contamination
during the curing period.
